Generally, it is used to reduce the thickness of the steel substrate, and spray several more coatings on the steel substrate or choose a very thick coating. Thus affecting the overall degree of the sandwich panel.

2. Observe whether the exposed steel of the sandwich panel, such as the section, can crystallize finely, and whether it can be gray, dark and impurities. If the section is fine crystalline, the quality is better.
